Trying to find a serial

A young woman (about 25 years old) is sentenced to join a well-to-do family for one year. I think the father was the mayor. She's got to attend the local school too even though she's actually finished her education. In the family there is one girl who leaves her alone but also a boy who lusts after her and manages to have her whipped by mother and father in order to have an eyeful.
Can anybody remember the author or the title?

It sounds a bit like one of ImReadOnly2's stories.

I can tell you that it definitely exists somewhere here in the LSF. I remember it well, but unfortunately not well enough to help you with a title or an author reference.

Ah, well... Considering there are 23.932 items in the library I just hoped the author would answer me.

It sounds like it may be "the Coming of the Brotherhood" by our wonderfully talented Dr Keate

Thanks a lot, it's that one!
